15 obsolete words we should still be using

Over time, some words fall into disuse, but that doesn't mean they aren't valuable.

Language is constantly evolving as word meanings shift, new words emerge and others go out of style.

This fluidity is due to several factors. First, language changes along with our needs. As new technologies and experiences arise, we label them and create new words to describe them — like texting and Googling.

The creation of communication technologies like the Internet can even lead to entirely new sociolects — social dialects associated with certain groups — like lolspeak and leetspeak.

We also borrow words from other languages (sushi, kayak), combine them to create new words (motel, brunch) or shorten them to make new ones (phone, gym).

Language also evolves because no two people have the exact same language experience. Our lexicon can vary depending on our location, culture, occupation and education, and age can play a significant role as well.
